The puzzling story of flare inactive ultra fast rotating M dwarfs -- III. Investigating X-ray Activity
Lauren Doyle, George W. King, Gavin Ramsay +4
According to activity-rotation relations, rapid rotators are expected to show high levels of magnetic activity. However, recent studies with TESS have found Ultra Fast Rotating (UF…

Characterising high and low accretion states in VY Scl CVs using ZTF and TESS data
C. Duffy, Kinwah Wu, G. Ramsay +4
VY Scl binaries are a sub-class of cataclysmic variable (CV) which show extended low states, but do not show outbursts which are seen in other classes of CV. To better determine ho…
